Well the only protection that gives you pitch-up is high-speed protection and I have reasons to believe that the aeroplane was nowhere near its Vmo of 350 kt on DME arc. Protections are also designed to shut themselves off if there are discrepancies between all three air data or inertial reference sensors.

Another protection that gives you pitch up, even though as a byproduct, is if you are close to stall and the protection gives you full power. With the engines at full power and slow speed, you will get a pitch up. Even though the alpha floor is not designed to give you pitch up, the pitch up at very slow speed might not be overrideable.
